AI Technical Summary

Benefits of technology

The present invention is a touch-control tire pressure sensor device that can be directly triggered to output a signal without any special tool. The device comprises a housing with an air nozzle, a circuit board with a processor and memory unit, and a pressure sensor unit, temperature sensor unit, acceleration sensor unit, LF transmission interface, RF transmission interface, touch control IC, battery pack, and a conducting plate. The touch control IC can be induced to output a logic signal to the processor and memory unit when triggered by an external conductive object to cause a change in electrical charge. The device provides a convenient and efficient solution for tire pressure monitoring.

Problems solved by technology

However, because a magnet or low frequency setting tool is not readily available, it is not so simple to enable the tire pressure sensor of a vehicle tire to output a wireless signal by using a magnet or low frequency setting tool.
The operation procedure of this re-learning mode is troublesome.

Abstract

A touch-control tire pressure sensor device includes a housing holding an air nozzle at one side thereof, a circuit board accommodated in the housing and carrying a processor and memory unit having electrically coupled thereto a pressure sensor unit, a temperature sensor unit, an acceleration sensor unit, a LF transmission interface and a RF transmission interface for transmitting a sensed signal to an on-vehicle main unit, a battery pack providing the circuit board with the necessary working voltage, and a conducting plate having one end connected to the touch sensor IC and an opposite end kept in contact with the air nozzle.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application is a continuation-in-part application of U.S. application Ser. No. 13 / 367,874 filed on Feb. 7, 2012. The disclosure of which is herein incorporated by reference in its entirety.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The present invention relates to tire pressure monitoring technology and more particularly, to a touch-control tire pressure sensor device.[0004]2. Description of the Related Art[0005]A tire pressure sensor device generally provide a re-learning mode for enabling an on-vehicle main unit to memorize the identification code of each of the four wheels of the vehicle carrying the on-vehicle main unit. Subject to the respective identification codes, the on-vehicle main unit can recognize the data of each of the four wheels and display the temperature, tire pressure and other related data of the respective wheel. If a wheel tire abnormality occurs, the on-vehicle main unit can give a warning...
